Title: Active matrix type el display device and its driving method
Inventor: TSUGE HITOSHI
IPC: H05B33/14
Filed: 2001-11-14
Abstract: PROBLEM TO BE SOLVED: To solve the problem wherein, in an active matrix type display device performing current drive, since the time constant by the product of the resis tance of a driving transistor and the stray capacity of a source signal line is large, the changing of the current value of the source signal line is slow. SOLUTION: In this display device, even when the time constant is large, a prescribed current value is made to be able to be written in pixels by diving a display area into two parts and, moreover, since the stray capacity of the source signal line becomes to be roughly half, the time constant is also made smaller. As a result, the prescribed current value becomes to be written in the pixels in a row selection period even in a low current area and when a frame frequency is fast and the signal is of low luminance, gradation displaying becomes possible.
